Figure Eight: School House Rock video about multiplying by Eight.

Lyrics

Figure eight as double four
Figure four as half of eight
If you skate, you would be great
If you could make a figure eight
That's a circle that turns 'round upon itself

1 x 8 is 2 x 4
4 x 4 is 2 x 8
If you skate upon thin ice
You'd be wise if you thought twice
Before you made another single move

1 x 8 is 8, 2 x 8 is 16
3 x 8 is 24, 4 x 8 is 32
And 5 x 8 is 40, you know
6 x 8 is 48, 7 x 8 is 56
8 x 8 is 64, 9 x 8 is 72
And 10 x 8 is 80, that's true

11 x 8 is 88, an' 12 x 8 is 96
Now here's a chance to get off
On your new math tricks
'Cause 12 x 8 is the same as 10 x 8
Plus 2 x 8
80 plus 16: 96

1 x 8 is 8, 2 x 8 is 16
3 x 8 is 24, 4 x 8 is 32
And 5 x 8 is 40, you know

Figure eight as double four
Figure four as half of eight
If you skate, you would be great
If you could make a figure eight
That's a circle that turns 'round upon itself

Place it on it's side and it's a symbol meaning infinity
